Convert files to and from KMZ
If a KMZ file is difficult to handle, you might try converting it to formats such as DXF, JPEG, OBJ, PDF, DAE or similar, which may be easier to work with.
Be aware that converting a KMZ file may reduce some features, but you can usually revert it to the original format.
With applications like MyGeodata Cloud, you can convert KMZ files offline while keeping the original quality intact.
